铬刚玉由拜耳-氧化铝与添加剂氧化铬在2100摄氏度以上的电弧炉中冶炼，中熔合而成。氧化铬的冲击韧性比白刚玉高一点。由于铬含量不同，我们分别提供淡粉红，粉红和红宝石三种颜色。随着氧化铬含量的增加，颜色变得越来越深，晶粒变得越来越硬。
　　1、铬刚玉是以氧化铝粉为主要原料，适配氧化铬，经高温电弧炉熔炼而成。
　　2、颜色呈粉红色、硬度近似于白刚玉，韧性比白刚玉高。用其制造的磨具，耐用度好，磨加工光洁度高等特点。
　　3、适用于量具、机床主轴、仪表零件、螺纹工件磨等精密磨削。
　　Pink fused alumina is produced by fusion of Bayer-alumina with additive Chromium oxide in an electric arc furnace at over 2100 centigrade. The Chromium oxide impact a bit higher toughness than White fused alumina. Due to different Chromium content, we separately provide 3 types of Light pink, Pink and Ruby. Along with chromium oxide content increased, the color become more and more dark and the grains become more and more tough.
